- I The invention relates to railroad track' structures and especiallyto railroad track g structures wherein the ties are formed from metal.

i The object of the invention is to provide an improved form andconstruction of anticreeping arrangement for both the rails andthe-ties, andfor a consideration of what I believe to be noveland myinvention, attention is directed-to the following specifica- 5 tion andthe claims appended thereto.

In the drawing, Fig. 1 is a top plan View of a track structure embodyingmy inven- 'tion, and Fig. 2 is a perspective view thereof. Referring tothe drawing, 1 indicates go track ties which are formed of ,metal andwhich embody as a part of their structure .7 angle bars 3 and 4 locatedat opposite ends l of the tie. In the present instance each-tie is shownas comprising two lengths of tie 5 bars 5 and 6 which are fastenedtogether at I their ends by the angle bars 3 and 4 and on their topsurfaces by plates 7 and 8 which 7 form supports for the track rails.The plates 7 and 8 are shown as being standard 7 o tie plates and theyare welded in place as is illustra'ted at '9. The rail positioning and.

holding rib of the tie plates is indicated at '10.. In the tie platesare two spaced openings 11 and- 12 between which the base flange of thetrack rail lies. The-head of the track 'rail isindicated at 13, the webis indicated at 14 and the base flange is indicated at 15.

r The rail is fastened to the-ties by fastening means comprising twomembers, a rail clamping member 16 and a fastener 17. The

rail-clamping member comprises a short U- -shaped bar having a central.portion 18* which lies in the tie plate opening,-an -upper inturned end19 which projects over thebase I flange of the rail and a lower inturnedend .20 which extends beneath thetie plate. 'It is held in place by-thefastener 17 which-is in of my present invention, the track tie structareforming the subject matter of my Pat 'ent 1,657',241 January 24, 1928,and the fastenin means forming the subject matter of .86 my. atent-1,657,242,'a1ready to.

applied.

They are illustrated onlybyway ofexample and are to be taken as typicalof any suitable construction to which my invention may be According tomy "invention, I make the an- -v le bars 3 and4 at the ends of the tiesof a length-such that they abut against each other as is indicated at21, and I- then provide at vsuitable points on the rail base flangesprojections 22 which stand on opposite sides of the end 19 of a railfastener. Projections- 22 may be built up-by fusing metal to the railflange, using a-welding machine for the purpose, or they may be formedon the rail when itis rolled. Projections 22 need be provided only atspaced points, it beingunnecessary to provide them-at eve tie. o fact,at one tie withinthe length 0 each rail may be suflicient. With thisarrangement,

creeping of the rail is prevented by'projections 22 engaging ends 19ofthe rail fasten ers. And the abutting angle barsat'the ends of theties serve to distribute the stress among theseveral ties so that thestress is not borne by the single tie appurtenant to thepiojections 22.Since the anglebars at other, each individual tie is held fromdisplacement by the adjacent ties. v By the above-described arrangement,therefore, ,wherein I provide abutting flanges orprojections 3,4 at theends OfjhG tIGS which flanges OIf'PIOjGCtlQIlS form apart of 'the endsof the successve ties abut one anthe ties in combination withprojections 22 appurtenant to certain of'the ties and which trackstructure wherein the ties mutually support one another against.displacement and one wherein the rails are held from creeping. Bythusproviding the abutting projections on the ties, I obtain the impor- I VI I .prevent creeping. of'the rails, I provide. 2.

tant result that it becomes necessary to;pro-. vide rojections 22 on butfew ties per rail 'lengt it being in fact necessary inmost instances toprovide projections 22 appurte- "nant to but one tie per rail length.This serves to simplify the'structure and makes it possibleto provide.the anti-creeping arrangement at low cost. v

-The use in the combination of an le bars '3 and 4 at theends of theties a ter the manner illustrated is of' especial utility since I v thevertical partsior plates of the angle bars serveto anchor the ties'inthe ballast against endwise movement while theabutting of the I What Iclaim as new and desire to secure by Letters Patent of the UnitedStates, is

1. In a track structure, the combination of a plurality of ties havingabutting projections at their ends whereby'the ties mutualwhich form apart of the tie structure, the

angle irons of'adjacent ties abutting each other, a rail on the ties,and abutting projections on the rail and at least one of the ties toprevent creeping of the rail.- 7

In a track structure} the combination of a plurality of ties, eachtie having transversely-extending platesv at its ends which projectbeyond the confines of the tie and I0 ly su port each other, a raiLonthe ties, and abutting projections on the rail and at least on of theties to prevent creeping of the ral '2. In a track structure, thecombination of ll a plurality of ties, each tie havingtransversely-extending angle irons at its ends form a part of the tiestructure, the plates I of adjacent. ties abutting each other wherebythe ties serve to. mutually support one another.
